Police know the identity of the second person they're looking for in connection to the murder of Officer Moses Walker and are still asking for the public's help to find him.

City police and federal law-enforcement authorities are searching for the suspect Thursday, said Homicide Capt. James Clark, who declined to release the suspect's name.

"we know he has people who are with him," he said.

Rafael Jones, who was taken into custody as a person of interest in Walker's slaying Wednesday, remains in custody but has yet to be charged. Clark, who did not identify Jones by name, said that the first suspect is still being interviewed by homicide detectives.

The reward for information in the case is $118,000. Tipsters should call 215-686-3334, or 215-686-8477, text PPD TIP (773847) or submit a tip online at phillypolice.com/forms/submit-a-tip.
